Fuji Question Re Updating Tamron Lens on Fuji body

Just wondering if anyone has been able to update a Tamron lens on a Fuji body.
Just tried to update my Tamron 18-300 on my X-T4 today.

X-T4 updated to v 1.5 OK
but Tamron would not update at all. Returned the error message on the Tamron firmware page

Firmware Upgrade Has Been Cancelled, Turn Off the Camera

Double checked the battery was at 100% and it was, tried a second time after another download same error.

Hope I dont have to send the lens to Tamron as that would not be worth the cost of shipping

Any Ideas ?
